If you are not sure why your geyser is making a loud noise, the first thing to consider is if there is a problem with the heating element or thermostat. These are common causes of geyser noises and can be easily rectified by flushing the appliance.
faulty heating element
A loud noise coming from your geyser may be caused by a faulty heating element. Water heaters are made from steel tanks and this can cause them to expand and contract. Similar noises can also be produced by metal pipes when heated above 125 degrees Fahrenheit. An electric water heater’s heating element is usually placed vertically in relation to the tank. This means that it can cause vibrations when water flows around it. You can correct this problem by tightening the element.
A faulty heating element can also cause the water to pass through sediment and create a rumbling noise. If the water is dirty, it will cause the heating element to be less effective and use more energy. Lastly, the element can be loose, causing it to produce humming or crackling noises. If you notice persistent crackling noises, call a plumber to check the unit.
If the noise continues, it may be a faulty valve. If this is the case, check the valve and check for a corroded component. You may also find a faulty gas regulator. Another possible cause of loud noise in a geyser is thermal expansion among parts of the water heater.
faulty thermostat
A faulty geyser thermostat can cause your home’s hot water to boil quickly, resulting in an overheated water tank. This is a serious problem, and it needs to be addressed immediately. Fortunately, there are a few fixes you can try to stop this problem from becoming a problem.
The first step is to diagnose the problem. If the noise is coming from the geyser, the problem is most likely the thermostat. Check to see if your tank is over-heated, as this can cause the noise. If your tank is too hot, try turning down the thermostat to make it more comfortable. If this doesn’t solve the problem, contact a heating professional to check for a defective thermostat.
Another option is to check the inlet control valve. This valve is often the culprit of a high-pitched noise. If you can open the valve, water will flow through it more easily. However, if you cannot find this valve, you may need to replace the valve at the water heater. This process can be dangerous, so it’s best to call a professional.
Another common cause of this noise is pooling water around the water heater. This water can interfere with the electrical components, causing the noise. It’s best to avoid the problem if you can. It’s also important to check that your water heater is turned off at night.
